DESCRIPTION

Products of spray-dried washing or cleaning agents

The present invention relates to a specific spray drying product, comprising silicate or silicates, surfactant or surfactants, support material. It also refers to washing or cleaning agents comprising such a spray drying product.

Spray drying, in many of the important technologies such as, for example, food technology and biotechnology, is one of the most important types of convection drying of particularly temperature sensitive substances and has been successful in repeated occasions in relation to the production of the most diverse items, such as, for example, powdered milk, instant coffee or pharmaceutical preparations.

In particular, spray drying is a well established process in the production of washing agents in powder form. Despite the fact that in modern production of washing agents spray drying has been displaced by other technologies, such as, in particular, mixing and extrusion technologies, there is still a very large need, particularly in the agent industry for washing and cleaning, of suitable spray drying products, see US 4 075 117.

A particularly important quality characteristic of spray drying products is grain stability. If it is not sufficiently guaranteed, considerable problems can occur during the subsequent processing of the spray drying products and also during the storage of the spray drying products.

Against this background, the objective of the present invention was to provide a spray drying product characterized by good grain stability.

Surprisingly, it was found that this objective is met by the object of the invention, in particular a spray drying product comprising silicate or silicates, surfactant or surfactants, support material, containing the spray drying product

a) ≤ 5% by weight of water-soluble polycarboxylate copolymers, in particular copolymers based on acrylic acid and maleic acid b)> 7% by weight of silicates, c) <15% by weight of anionic surfactant,

as well as 0.01 to 5% by weight of water-soluble polycarboxylate homopolymers, the% by weight in relation to the entire spray drying product.

This spray drying product is characterized, in particular, in an advantageous way because it has, even with slight apparent weights, a reduced polycarboxylate copolymer content and a reduced anionic surfactant content, a surprisingly good grain stability. Other advantages of this spray drying product lie in a very good water solubility, storage stability, and good flow properties.

The stability of surprisingly good grain can be particularly advantageously guaranteed advantageously when the polycarboxylate copolymer content is further reduced, that is, when it is advantageously from 0.01 to ≤ 3% by weight, preferably ≤ 1% by weight , more advantageously ≤ 0.5% by weight,% by weight in relation to the entire spray drying product and, in particular, when no copolymer of water soluble polycarboxylate is contained at all. This corresponds to a preferred embodiment of the invention.

Suitable polycarboxylate copolymers are, in particular, those of acrylic acid with methacrylic acid and acrylic acid or methacrylic acid with maleic acid, for example copolymers of acrylic acid with maleic acid containing from 50 to 90% by weight of acrylic acid and of the 50 to 10% by weight maleic acid. As a general rule, the relative molecular masses are in the range of 500 to 10,000 g / mol, preferably 2000 to 6000 g / mol and, particularly preferably, 3000 to 5000 g / mol. In the case of these molar masses, in the sense of the present document, they are about weight average molar masses Mw of the respective form of acid that have been determined primarily by gel permeation chromatography (GPC), a detector having been used UV In this regard, the measurement was performed against an external standard of polyacrylic acid that provides, because of its structural relationship with the polymers examined, realistic molar weight values. These indications clearly differ from the indications of molar weight in which polystyrene sulfonic acids are used as the standard. The molar masses measured against polystyrenesulfonic acids as a rule are clearly larger than the molar masses indicated herein.

There is another preferred embodiment of the invention when the spray drying product contains 8-30% by weight, preferably 8-25% by weight, advantageously 8-15% by weight of silicate or silicates. In particular, 10-12% by weight of silicate or silicates in the spray drying product, the% by weight in relation to the entire spray drying product, is suitable. The corresponding products show the advantages mentioned above in a particularly clear manner.

As silicates, salts, in particular alkali metal salts, of the different silicic acids can be used. Particularly suitable are sodium silicates, preferably amorphous sodium silicates, for example, amorphous sodium silicate with a Na2O: SiO2 module of 1: 2 to 1: 3.3. In particular, soluble silicate may be contained as silicate. This corresponds to a preferred embodiment of the invention.

As already shown, the spray drying product according to the invention is advantageously characterized in that it exhibits surprisingly good grain stability despite the reduced content of anionic surfactant. A possible lower limit of the anionic surfactant content of the spray drying product can be found, for example, in 0.01% by weight,% by weight in relation to the entire spray drying product. When the spray drying product according to the invention contains anionic surfactant, which advantageously comprises alkylbenzenesulfonate, such as, preferably, linear alkylbenzenesulfonate (LAS), advantageously in amounts of 0.01-14% by weight, more advantageously 3-13% by weight, in particular in amounts of 5-12% by weight,% by weight in relation to the entire spray drying product, then there is a preferred embodiment of the invention.

As already described, surprisingly good grain stability can be guaranteed despite the fact that the polycarboxylate copolymer content is substantially reduced.

Advantageously, the part of homopolymers (water soluble) of polycarboxylate may also be reduced. A spray drying product according to the invention containing 0.01-5% by weight of polycarboxylate homopolymers (water soluble), such as in particular homopolymers based on acrylic acid, advantageously 0.01% in weight at <3% by weight, preferably less than 1% by weight of polycarboxylate homopolymers (water soluble), therefore corresponds to a preferred embodiment of the invention. The indication of% by weight refers to the entire spray drying product.

Suitable polycarboxylate homopolymers are, for example, the sodium salts of polyacrylic acid or polymethacrylic acid, for example those with a relative molecular mass of 500 to 10,000 g / mol, preferably 2000 to 6000 g / mol and in particular 3000 at 5000 g / mol. Also in the case of these molar masses it is, in the sense of the present document, of molar masses average in weight Mw of the respective acid form, which have been determined mainly by gel permeation chromatography (GPC), having used a UV detector, as described above.

As support materials are considered for the spray drying product according to the invention, in particular, those that are selected from carbonates, sulfates, zeolite, sodium tripolyphosphate and / or chlorides. They are carbonates which may preferably be used alkali metal carbonates such as, for example, in particular sodium carbonate or, for example, sodium hydrogen carbonate, with sodium carbonate being particularly preferred. Particularly preferred sulfates are alkali metal sulfates such as, for example, sodium sulfate, but also alkaline earth metal sulfates such as, for example, magnesium sulfate. Particularly preferred chlorides are in particular alkali metal chlorides such as, preferably, sodium chloride.

When the content of support metal in the spray drying product according to the invention is 5-90% by weight, preferably> 50% by weight, in particular> 60% by weight, in relation to the entire product of spray drying, then there is a preferred embodiment of the invention.

Advantageously, the spray drying product according to the invention also contains complexing agents such as, in particular, phosphonate, for example, in amounts of ≥ 0.01% by weight to 3% by weight,% by weight in relation to All spray drying product. This corresponds to a preferred embodiment of the invention. Other complexing agents useful in washing or cleaning agents can also be used.

It has also been found that the presence of cellulose ether and / or its salts in the spray drying product according to the invention can also advantageously contribute to a further improvement in grain stability. If the spray-drying product according to the invention therefore contains cellulose ether and / or its salts such as, in particular, carboxymethyl cellulose, for example, in amounts of ≥ 0.01% by weight at 3% in weight, then this corresponds to a preferred embodiment of the invention.

The spray drying product according to the invention advantageously has an apparent weight of ≤ 500 g / l, in particular the apparent weight is in the range of 400-500 g / l.

The spray drying product according to the invention can now be used as an independent washing or cleaning agent.

It is also possible to mix or combine the spray drying product according to the invention with other components. In particular, it is possible to add thermolabile constituents such as, for example, bleaches or perfumes by subsequent mixing to the spray drying product according to the invention.

Therefore, another object of the invention is a washing or cleaning agent containing a spray drying product according to the invention.

Possible ingredients that may be preferably contained in a washing or cleaning agent according to the invention are described in more detail below.

In addition, a spray drying process is disclosed in which an aqueous suspension is used containing

4 to 12% by weight of silicate or silicates,

5 to 12% by weight of anionic surfactant, in particular LAS,

40 to 60% by weight of support material, in particular sodium carbonate and / or sulfate,

from 20 to 60% by weight of water as well as

less than 2% by weight of polycarboxylate copolymers,

% by weight in relation to the entire aqueous suspension.

Spray drying as such can be carried out according to the usual procedures for the preparation of washing or cleaning agents in powder form. The first stage of a usual spray drying process in the general case is the preparation of an aqueous suspension (liquid slurry) of the washing agent ingredients to be spray dried which, under the conditions of spray drying, advantageously neither volatilize nor decompose. This liquid paste generally comprises surfactants, auxiliary substances and usually adjusting agents. The liquid paste is then transported through pumps to the spray tower and sprayed through nozzles located in the tower head. In this regard, the ascending hot air dries with a temperature of preferably 200 to 350 ° C the liquid paste and evaporates the adhered water. At the exit of the tower (temperature preferably 80-120 ° C) then dried fine powders are produced.

A general problem in spray drying is that too high step speeds can lead to wake formation and dust explosions. Another advantage of the present invention now lies in the fact that, in the case according to the invention, the performance of the spray tower can be increased, that is, the speed of passage, without resulting in the indicated disadvantageous effects.

Another advantage is that the process makes it possible to obtain spray drying products reduced in surfactants and reduced in polymers that have a very good grain stability without having to adjust very high apparent weights.

This is particularly advantageous because an increasing number of consumers have the desire to be able to act more individually in the dosage of washing or cleaning agents. But if now the washing agent

or cleaning is very concentrated, so the consumer's freedom of dosage, because of the small amount of the agent to be dosed, is more limited than in the case of less concentrated agents. The consumer, therefore, increasingly demands washing or cleaning agents with a reduced apparent weight that, despite this, must have a good grain stability. This desire is satisfied with a process for the production of washing or cleaning agents with an apparent weight in the range of ≤ 500 g / l by spray drying of an aqueous suspension containing

4 to 12% by weight of silicate or silicates,

5 to 12% by weight of anionic surfactant, in particular LAS,

40 to 60% by weight of support material, in particular sodium carbonate and / or sulfate,

from 20 to 60% by weight of water as well as

less than 2% by weight of polycarboxylate copolymers,

% by weight in relation to the entire aqueous suspension.

In addition, the use of 4% by weight to 12% by weight of silicate or silicates in aqueous suspensions to be spray dried is disclosed to improve the grain stability of the spray drying product, the% by weight relative to the entire suspension. watery

Particularly preferred are alkyl sulfates having a lower Krafft point, preferably with a Krafft point less than 45, 40, 30 or 20 ° C. Krafft's point is the designation of the temperature at which the solubility of surfactants is intensely increased as a result of micelle formation. The Krafft point is a triple point where the solid body or hydrated crystals of the surfactant are in equilibrium with its dissolved (hydrated) monomers and micelles. The Krafft point is determined by an opacity measurement in accordance with DIN EN 13955: 2003-03.

A reasonable upper limit of zeolite can be found, for example, at 60% by weight, 50% by weight or 40% by weight in relation to the entire agent. This corresponds to a preferred embodiment of the invention.

Within the meaning of the invention, the term "support system" also includes those "systems" that are composed of only a single support such as, for example, zeolite. But it is preferred to use at least 2 substances with a support effect, for example, zeolite in combination with sodium carbonate or the like.

It is also particularly preferred when the washing or cleaning agent according to the invention contains a soluble support system, which preferably comprises sodium carbonate, silicate, citrate and / or polycarboxylates, advantageously in amounts of 0.1-50% in weight in relation to the entire agent. This corresponds to a preferred embodiment of the invention.

The ingredients mentioned above are now partly described in greater detail.

The washing or cleaning agents according to the invention preferably contain, as already described, a surfactant or even several surfactants, in particular anionic surfactants, nonionic surfactants and mixtures thereof, but also cationic, zwitterionic and amphoteric surfactants.

The nonionic surfactants that can be used have already been mentioned. Suitable non-ionic surfactants are, in particular, alkylglucosides and ethoxylation and / or propoxylation products of linear or branched alkylglucosides or alcohols with, respectively, 12 to 18 C atoms in the alkyl part and 3 to 20, preferably of 4 to 10 alkyl ether groups. In addition, the corresponding ethoxylation and / or propoxylation products of N-alkyl amines, neighborhood diols, fatty acid esters and fatty acid amides which, in relation to the alkyl part, correspond to the alcohol derivatives of mentioned long chain, as well as of alkylphenols with 5 to 12 C atoms in the alkyl moiety.

As nonionic surfactants, preferably alkoxylated, advantageously ethoxylated, especially primary alcohols are used, preferably with 8 to 18 C atoms and an average of 1 to 12 moles of ethylene oxide (OE) per mole of alcohol optionally, in which the alcohol moiety can be linear or preferably have methyl branching in position 2 or it can contain mixed linear and branched methyl moieties, as they usually appear in oxoalcohol moieties. However, in particular alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 C atoms are preferred, for example, of coconut, palm, tallow or oleyl fatty alcohol and on average 2 to 8 OE per mole of alcohol Preferred ethoxylated alcohols include, for example, C12-C14 alcohols with 3 OE or 4 OE, C9-C11 alcohols with 7 OE, C13-C15 alcohols with 3 OE, 5 OE, 7 OE or 8 OE, C12-C18 alcohols with 3 OE, 5 OE or 7 OE and mixtures thereof, such as mixtures of C12-C14 alcohol with 3 OE and C12-C18 alcohol with 7 OE. The indicated degrees of ethoxylation represent statistical mean values that for a special product can be a whole or fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these non-ionic surfactants, fatty alcohols with more than 12 OE can also be used. An example of this is fatty (tallow) alcohols with 14 OE, 16 OE, 20 OE, 25 OE, 30 OE or 40 OE. Particularly in agents for use in machine processes, compounds which are usually extremely poor in foam can be used. To this belong, preferably, C12-C18 alkylpolyethylene glycol-polypropylene glycol ether with, respectively, up to 8 moles of units of ethylene oxide and propylene oxide in the molecule. But other non-ionic surfactants which are known to be poor in foam, such as, for example, C12-C18 alkyl polyethylene glycol polybutylene glycol ether with, respectively, up to 8 moles of ethylene oxide and butylene oxide units in the molecule can also be used as well as mixed closed alkyl polyalkylene glycol ethers with terminal group. Particularly preferred are also alkoxylated alcohols containing hydroxyl groups, as described in European patent application EP 0 300 305, the so-called mixed hydroxyethers. Alkylglucosides of the general formula RO (G) x in which R represents a primary aliphatic straight-chain or branched-chain aliphatic moiety, in particular methyl branching in position 2, with 8 to 22, preferably belong to the non-ionic surfactants 12 to 18 atoms of C and G represents a unit of glycosa with 5 or 6 atoms of C, preferably represents glucose. The degree of oligomerization x indicating the distribution of monoglycosides and oligoglycosides is a discretionary number - which as a variable to be determined analytically can also adopt fractional values - between 1 and 10; preferably x is 1.2 to 1.4. Also suitable are fatty polyhydroxy acid amides of formula (III) in which R 1 CO represents an aliphatic acyl radical having 6 to 22 carbon atoms, R 2 represents hydrogen, an alkyl or hydroxyalkyl radical having 1 to 4 carbon atoms and [Z] represents a linear or branched polyhydroxyalkyl moiety with 3 to 10 carbon atoms and 3 to 10 hydroxyl groups.

Preferably, the fatty polyhydroxy acid amides are derived from reducing sugars with 5 or 6 carbon atoms, in particular from glucose. Compounds of formula (IV) also belong to the group of fatty polyhydroxy acid acids,

wherein R3 represents a linear or branched alkyl or alkylene moiety with 7 to 12 carbon atoms, R4 represents a linear, branched or cyclic alkylene moiety or an arylene moiety with 2 to 8 carbon atoms and R5 represents a linear alkyl moiety, branched or cyclic or an aryl moiety or an oxy-alkyl moiety having 1 to 8 carbon atoms, C1-C4 alkyl or phenyl moieties being preferred and [Z] represents a linear polyhydroxyalkyl moiety, whose alkyl chain is substituted with at least two hydroxyl groups, or alkoxylated derivatives, preferably ethoxylated or propoxylated from this moiety. [Z] is also obtained here, preferably, by reductive amination of a sugar, such as glucose, fructose, maltose, lactose, galactose, mannose or xylose. Compounds substituted with N-alkoxy or N-aryloxy can then be converted, for example, by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst to give the desired fatty polyhydroxy acid amides. Another class of nonionic surfactants that can be used preferably, which can be used as the sole nonionic surfactant or in combination with other nonionic surfactants, in particular together with alkoxylated fatty alcohols and / or alkylglucosides, are acid alkyl esters alkoxylated fatty, preferably ethoxylated or ethoxylated and propoxylated, preferably with 1 to 4 carbon atoms in the alkyl chain, in particular fatty acid methyl esters. Nonionic surfactants of the type of amine oxides may also be suitable, for example, N-alkyl coconut-N oxide, N-dimethylamine and N-alkyl tallow-N oxide, N-dihydroxyethylamine and alkanolamides of fatty acid. The amount of these non-ionic surfactants preferably does not amount to more than that of ethoxylated fatty alcohols, in particular not more than half of this.

The anionic surfactants that can preferably be used have already been mentioned. As anionic surfactants, preferably those of the sulphonate and sulfate type are used. Surfactants of the sulphonate type are, in this regard, preferably alkyl-C9-C13-benzene sulphonates, olefin sulphonates, that is, mixtures of alken-e hydroxyalkane sulfonates as well as disulfonates, as obtained, for example, from C12-C18 monoolefins with double bond in terminal or internal position by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of sulfonation products. Also suitable are alkane sulphonates which are obtained from C12-C18 alkanes, for example, by sulfocloration or sulfoxidation with subsequent hydrolysis or neutralization. Also suitable are fatty α-sulfoacid esters (ester sulphonates), for example, α-sulphonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.

Other suitable anionic surfactants are sulfated fatty acid glycerin esters. By fatty acid glycerin esters, mono-, di- and tri-esters are understood as well as mixtures thereof, as obtained during the preparation by esterification of a monoglycerin with 1 to 3 moles of fatty acid or during the transesterification of triglycerides with 0.3 to 2 moles of glycerin. In this regard, sulfated fatty acid glycerin esters are sulfated products of saturated fatty acids with 6 to 22 carbon atoms, for example, of caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid , stearic acid or behenic acid.

As alk (en) yl sulfates, alkali metal and, in particular, sodium salts of sulfuric acid half esters of C12-C18 fatty alcohols, for example coconut fatty alcohol, tallow fatty alcohol, are preferred, lauryl, myristyl, cetyl or stearyl alcohol or of the C10-C20 oxoalcohols and of the secondary alcohol half esters of these chain lengths. In addition, alkyl (en) yl sulfates of the aforementioned chain length containing a synthetic straight chain alkyl radical prepared with a petrochemical base are preferred, which have a degradation behavior analogous to suitable compounds based on fat chemistry raw materials . In the interest of the washing technique, C12-C16 alkyl sulfates and C12-C15 alkyl sulfates as well as C14-C15 alkyl sulfates are preferred. Also suitable are anionic surfactants are 2,3alkyl sulfates that can be obtained as commercial products from the Shell Oil Company under the name DAN®.

Also the sulfuric acid monoesters of the C7-C21 straight chain or branched ethoxylated alcohols with 1 to 6 moles of ethylene oxide, such as C9-C11 alcohols with 2-methyl branching with, on average, 3.5 moles of ethylene oxide (OE) or C12-C18 fatty alcohols with 1 to 4 OE are suitable. They are optionally used in cleaning agents because of their high foaming behavior only in relatively limited amounts, for example, in amounts of 1 to 5% by weight.

Other suitable anionic surfactants are also salts of the alkylsulfosuccinic acid which are also referred to as sulfosuccinates or esters of sulfosuccinic acid, and the monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and, in particular, ethoxylated fatty alcohols. Preferred sulfosuccinates contain C8-18 fatty alcohol moieties or mixtures thereof. Particularly preferred sulfosuccinates contain a fatty alcohol moiety that is derived from ethoxylated fatty alcohols which, considered in themselves, represent non-ionic surfactants (description see below). In this regard, sulphosuccinates whose fatty alcohol residues are derived from ethoxylated fatty alcohols with a narrowed homolog distribution are particularly preferred. It is also possible to use alky (en) ilsuccinic acid with, preferably, 8 to 18 carbon atoms in the alky (en) yl chain or its salts.

Soaps are particularly preferred anionic surfactants. Saturated and unsaturated fatty acid soaps are suitable, such as salts of lauric acid, myristic acid, palmitic acid, stearic acid, erucic acid (hydrogenated) and behenic acid as well as, in particular, mixtures of acid derived soaps
